摘要

This paper summarizes the observation results of mantle tritium (~3H) in two volcanic lakes, Lakes Nemrut (Turkey) and Laacher (Germany). The presence of excess ~3H in the lakes can be explained as material released from mantle source because of the correlation of excess ~3H with mantle~3He and ~4He. We conclude that excess ~3H in these two lakes, after the origin of the excess ~3H from atmosphere and conventional nuclear reactions are excluded and the correlation of the excess ~3H and mantle ~3He is considered, might be from a mantle source and produced by nuclear fusion (d-d reaction) in the deep Earth. We have also investigated helium isotopes in the hydrothermal vent fluids at Mid-Ocean Ridge (MOR). The results show nearly constant ~3He/~4He ratio (~3He/~4He = 1.12 ± 0.13 × 10~(-5)) and approximately constant ~3He/heat ratios ((5-10) × 10~(-18) mol/J). The correlation of ~3He with ~4He and heat suggests that it is reasonable to suppose ~3He is produced by nuclear fusion (d-d reaction) and ~4He from a-decay of U and Th in the deep Earth. Based on that, ~3He/~4He ratios for 10 hydrothermal vent fluids are calculated. The results agree with the measurement at hydrothermal vent fluids and Mid-Ocean Ridge Basalts (MORB) on the average. We concludes that the narrow distribution of ~3He/~4He ratio peaked at ~ 8 R_A in MORB can be explained by the hypothesis that ~3He is produced in nuclear fusion.
